Emptiness formation probability and PainlevéV equation in the XY spin chain
(IOP Publishing Ltd and SISSA Medialab srl, 2020)
Rectification and one-way street for the energy current in boundary-driven asymmetric quantum spin chains
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAUFMG, 2017)
On the series expansion of the general spin-S Ising chain
(Physica A: statistical mechanics and its applications, 2019)
Spin-spin correlations between two Kondo impurities coupled to an open Hubbard chain
(American Physical Society, 2013-02)
In order to study the interplay between Kondo and Ruderman-Kittel-Kasuya-Yosida interaction, we calculate the spin-spin correlation functions between two Kondo impurities coupled to different sites of a half-filled open ...
Transmissão de emaranhamento através de cadeias de spins
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2018-04-25)
In this thesis we studied the transmission of entangled states in unmodulated spin chains using a slight modification in the XY isotropic model (XX model) that describes a one-dimensional spin-1/2 chain. We have shown that ...
Quantum theory of spin waves in finite chiral spin chains
(American Physical Society, 2014)
We calculate the effect of spin waves on the properties of finite-size spin chains with a chiral spin ground
state observed on biatomic Fe chains deposited on iridium(001). The system is described with a Heisenberg
model ...
Critical behavior of the 2D Ising model modulated by the Octonacci sequence
(IOP Publishing, 2020)
The coprime quantum chain
(IOP Publishing, 2020)
Towards the solution of an integrable spin chain
(2019-10-03)
Two branches of integrable open quantum-group invariant Dn+1 (2) quantum spin chains are known. For one branch (ϵ = 0), a complete Bethe ansatz solution has been proposed. However, the other branch (ϵ = 1) has so far ...
Dynamic properties of a classical anisotropic Heisenberg chain under external magnetic field
(ELSEVIER SCIENCE BV, 2005-01-31)
We investigate the dynamic properties of a classical anisotropic Heisenberg chain interacting with an external magnetic field at different temperatures. Properties such as time-dependent energy autocorrelation and space-time ...
